At modus health, we leverage our unequalled ability to accurately measure function in patients with slow or irregular gait.

In all types of clinical research, obtaining accurate data is absolutely vital. For clinical studies that require measuring a subject’s activity, getting this type of precise data can be difficult. The gait of study subjects with health conditions ranging from neurological disorders to cardiopulmonary diseases is not easily recorded using mechanical pedometers or traditional accelerometer-based step counting modalities. modus’ StepWatch™ has been proven accurate at measuring walking where these other monitors are not.

measure what matters

We seek to improve healthcare outcomes through precise, evidence-based decision making.

modus combines the highly sensitive instrumentation of the StepWatch™ with modus’ proprietary algorithmic data analysis software to provide you with the objective and accurate data you need to make informed clinical decisions.

With its rich scientific history and validated accuracy, the modus StepWatch™ has application in a broad range of research activities where measurable, reliable data on ambulation are required. The system is currently being used by many of the top academic medical centers, universities and health systems, clinical research organizations, and pharmaceutical companies around the world.

Data Recieved

capturing a story
in every step

By measuring steps walked throughout the day, clinicians and researchers can trace patterns in a person’s lifestyle. Changes in step count can be indicative of new risk or show the efficacy of certain interventions and treatment plans. Steps also can help clinicians monitor progress in patients who, for example, have experienced stroke or trauma.

Every step a person takes tells a story; but for that story to translate into effective research findings or clinical interventions, the data must be accurate. Researchers have found that an accurate step count helps patients visualize their progress and work more successfully toward their goals. With inaccurate metrics, it is easy for a patient to become disheartened.

The modus StepWatch™ activity monitoring system has been clinically proven and validated to provide the most accurate measurements of physical activity in persons with slow gait, or irregular gait due to disease or disability. The modus technology has been validated in over 360 peer-reviewed publications, with accuracy consistently reported at over 98%. The modus StepWatch™ system enables you to objectively assess your patients’ progress through data-driven solutions which may support enhanced levels of care to achieve improved clinical outcomes.

don't take our word for it,
here's the proof
